WILLIAM R. SANTLEY, OF WVELLINGTON, OHIO.

MACHINE-BELT HOLDER.

SPECIFICATION forming part of Letters Patent No. 298,238, dated May 6, 1884.

Application filed October 5, 1883. (No model.)

To all whom il'i'WbLY/Z/ concern:

Be it known that I, WILLIAM R. SANTLEY, of WVellington, in the county of Lorain and State of Ohio, have invented a certain Improved Machine-Belt "Holder; .and I do hereby declare the following to be a full and complete description thereof.

The said invention relates to a machine-belt holder upon which a belt is shifted from a live pulley or drum and held in a slackened state at rest when not required for use.

The invention consists of a differential curved or segmental rim, in the face of which are transverse slots or openings for rollers, which have their pivotal or axial supports in proj ections from the said rim. To the interior face of the rim is attached one or more braces, which may be arranged in sections for supporting and strengthening the rim with the rollers.

The belt-holder herein set forth may be held and sustained in relation to a driving-pulley in any suitable position and by ordinary means without departing from the nature of the said invention.

For a more full and complete description of the construction and operation of the said beltholder reference will be had to the following specification, and to the annexed drawings, making part of the same, in which Figure lis a face or front view of the holder; Fig. 2, a side view, and Fig. 3 an inside view of the said holder opposite to that of Fig. 1.

' Like letters denote like parts in "the several drawings.

The said invention is supported in position at the side of alive pulley or drum upon a line of shafts, and so arranged that the belt may be shifted from the pulley or drum, when not in use, onto the holder, and then slackened and at rest, thereby preserving the belt from needless wear and strain, and a relaxation of the belt-tension from the strain when upon the live-pulley. The holder may be of any desirable size to correspond with and according to the diameter of the pulley for which it is designed.

In the rim A are a series of transverse slots, B, in which are rollers 0, having pivots rim A on both sides, in which the roller bearings or pivots can be supported in line with the slots B, essentially thesame as when journaled in the arms or ears E. The rim of the holder is formed in differential curves or seg ments. From a to bis the segment of the pulley-circle, and from b to c isless than from a to b, or converges toward the aXis of the rim. By this construction the belt will be slackened when shifted upon the rim A from the live-pulley, as the holder is placed in such close proximity to the pulley as to be readily shifted from one to the other by the ordinary devices and mechanism used for shifting belts. The rim Ais stiffened and strengthened by means of one or more stays or plates, F, Figs. 2 and 3, firmly attached to the interior face of the said rim, and connected with suitable means for supporting the holder in juxtaposition with the driving-pulley or drum.

In place of the brace 'or braces F, a frame or series of arms may be arranged in connection with the rim for strengthening and secur ing the holder in its place. 1

N o especial means are required to sustain the holder in its. relation to a live pulley or drum, as its construction and arrangement admit of various devices and means for this purpose.

The holder may be firmly held adjoining a driving-pulley or drum by braces, frame-work, or iron stays.

The manner and appliances required for sustaining the holder admits of such modifications as may be needed in adapting it to variouspositions without departing from the nature of the invention.

What I claim as my improvement, and desire to secure by Letters Patent, is

1. A machine -belt holder consisting of a combination of the rim A, having a differential peripheral curve, and transversely in the face thereof a series of slots, rollers journaled in said slots in suitable bearings at each end face of said rim, substantially as and for the thereof, and so adjusted that the face of the purpose set forth. rollers may be above the surface of the rim, In testimony whereof I aflix my signature in and one or more re-enforeing plates 01- braces presence of two Witnesses.

5 within the rim,substantially as herein set forth. XVILLIAM R. SANTLEY.

2. In combination with a series of rollers, Witnesses: 0, arranged within slots of the rim A, one or D. A. WILLARD, more braces or plates secured to the inner \V. H. SCHNEIDER.
